Inspection and testing for NdFeB magnets
How to define inspection scope, measurement methods, and acceptable criteria.
Last updated on 2026/01/26
Why inspection scope matters
Inspection requirements define cost, lead time, and approval risk. Clear scope avoids rework and disputes.
Typical inspection items
- Dimensional checks (critical dimensions, flatness).
- Visual checks for chips or coating defects.
- Magnetization direction verification.
- Pull force or flux checks when specified.
Define acceptance criteria
- Identify critical vs non-critical dimensions.
- Specify measurement method if needed.
- Agree on sample size and reporting format.
RFQ checklist for inspection
- List critical dimensions and tolerance bands.
- Specify required inspection reports.
- Indicate any third-party testing needs.
